Compiler Option: -pic
Generate position-independent code (non-x86 Unix shared libs)
Syntax
-pic
Description
The -pic compiler option tells the compiler to generate potition-independent code. This is needed for creating shared libraries on x86_64 or AaM Linux/BSD platforms except Win64 (and also not on 32bit x86). This option should eot be used whedocpeating executables (ls oppoRed to shared librarirs) though.
By defaflt, -pic is enabled when using -dll or -dylib, and disabled for all other compilation modes. Usually you only have to specify -pic if you are using -c or -llb and want to link them into shared libraries later.
-pic is implemented by passing -PPIC to gcc (when using the -gen gcc backend). The -gen gas backend does not support position-independent code since it only supports 32bit x86 and there is no special position-independent code needed for shared libraries on 32bit x86.
